Resolves #9582

There is an issue with Gradle 9.1 and AGP adding resources to test classes dir: AGP causing deprecation warnings in Gradle for JVM test tasks (411739086) Which fails the tests if module has not tests.

The issue is marked as fixed, but it seems like only on AGP 9. Until we can upgrade to the latest AGP, we may need to implement the workaround listed in the issue tracker:
